Instructional design is a science that has received little attention from residential universities and educational practices. Instructional design is regarded as a prerequisite for designing, delivering and optimising flexi-learning programmes and should be part of the curricularising processes of universities. There is furthermore an increasing awareness, both internationally and nationally, of the need for distance education. The paradigm shift towards more learner centred study, independent of time and place, necessitates the redesigning and development of learning material at tertiary institutions. This study applies the parameters of instructional design and distance teaching to the field of hearing aid acoustics. The stages utilised in the instructional design of a distance teaching program for hearing aid acousticians were the following: planning through an analysis of the situation, design and development of the program, implementing the postgraduate Diploma in Hearing Aid Acoustics and the utilisation and management of the program through continuous assessment of the program. In the planning phase an analysis of the situation was conducted by means of questionnaires to the major role players, viz. hearing aid dispensers in practice and their adult and geriatric clients with a hearing loss. A total of 144 respondents were included in the study. In the planning document the expected outcomes and main traits of the potential learners were identified. The best system for the delivery of the program was also selected. The results of the analysis phase were used to develop and implement a two year post-graduate distance teaching diploma in hearing aid acoustics. A major challenge was to effectively facilitate the practical skills required of hearing aid acousticians within a distance teaching program. Selected contact periods are therefore used for practising practical skills. In the final phase of instructional design, the program was evaluated. It was indicated that instructional design is indeed a prerequisite for specifying conditions for learning, based on sound teaching principles.
